UNITED STATES PATENT OFFICE JAMES A. PARK, OF LANSING, MICHIGAN, ASSIGNOR OF ON E-HALF TO PUELLA E. PARK, OF SAME PLACE.

HARNESS-SNAP;

SPECIFICATION forming part of Letters Patent No. 294,145, dated February 26, 1884.

Application filed April 24, 1882. Renewed July 6, 1883. (No model.)

To all whom, it may concern.-

Be it known that I, J AMES A. PARK, of the city of Lansing, in the county of Ingham, State of Michigan, have invented a new and useful Improvement in Harness-Snaps; and my invention has for its object to furnish a harness-snap that can be fastened to a strap without sewing, and to make the parts separate, so that if one be broken itcan be quickly and cheaply replaced.

Figure 1 is a sideview of my invention; and Fig. 2 is a middle longitudinal sectional view of my invention, showing how I fasten the strap inafter referred to.

and the parts of my snap together, and showing also one-half of the guide-slotF,which is heresnap in that it has only a hole to receive a bolt in the end opposite from the hook instead of a loop or ring to receive a strap. It has also an opening, -F, through which the spring passes from where it is fastened to the hook.

The bars of the frame on either side of the opening serve toguide the spring,and to keep it from moving sidewise out from under the hook and protect it from injury. I fasten the spring to the under side of the back part of the frame 0 above the strap. The bolt D passes through a hole in the back end of the frame, and through a hole in the end of the spring B, and through a hole in the end of the strap, and through a washer under the strap. The nut E is then put on and screwed up,

and thus all the parts of the snap are fastened in position, and the strap is fastened thereon at the same time. I make my spring straight, and when it loses its spring or stiffness by use it can be turned upside down. It will be seen that the spring bends over leather above the iron washer, and will, as a consequence, be more lasting than if it were bent over the sharp corner of metal, and that the spring is well protected from injury, owing to its being fastened underneath the ba ck end of the frame and receiving its protection there, and at the side by the side bars,which form the guide-slot F, as will be seen by reference to the drawings.

I can dispense with a nut for the bolt D by casting the hole in the back end of the frame 0 small enough and suitable to out theads therein for the bolt. In that case the head of the bolt would come where the nut now is, and the parts would be held together in the same manner as now.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is y In a harness-snap, the combination, with the frame provided with a hook, and a slot, F, of a spring adapted to extend through said slot and be guided by the adjacent sides of the frame, and secured to the. under side of the rear end of the frame, which latter is perforated to receive a fastening-bolt, a strap upon which said spring bears, a washer, and retaining-nut, substantially as set forth.
